getAttribute() in constructor

[luwes]

Just a heads up, I fixed a small bug in lite-vimeo.

this.getAttribute() should not be called in the custom element constructor as it's possible the attribute is not defined yet at that point. happens when the script tag comes before the <lite-youtube> element.

Yup, working on this in #28. Thanks for the details as to why this practice should be discouraged though, useful to have written somewhere.
